signaling channel 1, the combined second inputs of each signaling channel are connected to the output of delay element 4 and are the device output, the third inputs of each signaling channel 1, the combined third inputs of each signaling channel are connected to a pulse generator 5, the combined fourth inputs of each signaling channel are connected to the output element OR 3, the first and second outputs of each signaling channel 1 are connected, respectively, to the inputs of the elements OR 3 and 2.

The device works as follows.

In the initial state, the multi-position mechanism is in one of the fixed positions, for example, at point 1.

At the same time, on bus Call 15 of the first signaling channel 1 and at the output of the corresponding sensor 6.1 of the position, there are signals which, through elements AND 7. OR 12, cause the corresponding indicator 14 to glow in a steady green color, indicating that the multi-position mechanism is at point 1. N Tires The call of 15 other signaling channels 1 and at the outputs of the remaining sensors O 2 ... 6.P are no signals, the corresponding indicators 14 are not illuminated.

When a multi-position mechanism is called, for example, at point p-1, the signal on the bus disappears. Call 15 of the first signaling channel 1, the signal 15 appears on the bus of the corresponding signaling channel 1, and the signal output at the output of the corresponding sensor 6 (p-1) missing.

In this case, in the first signaling channel 1, the signal at the output of the element And 7 disappears. a signal appears at the output of the element BANGE 10, causing the signal at the output of the trigger 13 and, respectively, in the first vlode element AND 9, the second input of which receives pulse signals or generator 5 pulses Pulse signal from the output element AND 9 through the element OR 12 causes the indicator to glow 14 flashing green, indicating that the multi-position mechanism has been set in motion. In the process of moving the multi-position mechanism towards the call point, signals on the outputs of sensors 6.2, 6.3 ... 6 (p-2) appear sequentially, which arrive at the first inputs of the corresponding signaling channels 1 and cause the corresponding indicators 14 to glow green. Kz in a way, on the mimic is displayed

the trajectory of movement of the multi-mechanism.

As soon as the multi-position mechanism arrives at a predetermined p-1 point, the output of the position sensor 6 (p-1) and, accordingly, signals appear at both inputs of the And 7 (p-1) -th signaling channel element elements AND 7 and OR 12 cause a glow

the corresponding indicator 14 in a steady green light, indicating that. that the multi-item mechanism is at a given point.

At the same time, the signal from the output of the element And 7 is fed to the corresponding input of the element OR 12. From the output of which the signal goes to the combined fourth inputs of all signaling channels 1, returns the corresponding triggers 13 in

the initial state and stops the glow of all indicators of 14 previous signaling channels 1, i.e. The device is in the initial state and is ready for further operation.

If during the movement of the multi-position mechanism to a given point, a malfunction occurs preventing it from moving, the signal from the output of the BAN 11 element of the corresponding signaling channel 1 through the OR element 2 and the delay element 4 is fed to the second input of the And 8 element of the corresponding signaling channel. Since the first input of this element contains a signal from the bus Call 15, a signal appears at its output, which arrives at the second input of the corresponding indicator 14 and causes it to glow red, indicating that the multi-position mechanism 9 has not arrived. At the same time, a generalized signal about the occurrence of an emergency appears at the output of the device. In this case, the trajectory of the traversed path of the multi-position mechanism will be

display on the mnemonic circuit the flashing green color of the corresponding indicators 14, which will allow to determine the location of the multi-position mechanism with sufficient accuracy. For reliable operation

devices in determining faults; the delay time for the occurrence of a signal generated by delay element 4 must be longer than the maximum possible time for a multiposition mechanism to move from one call point to another.
